Clock-conversion file for the NISAR radar satellite

NISAR L-SAR Radar Clock to UTC Conversion File
land NASA ASF Level Not Provided active ASCII
In plain English

What it measures. A conversion file that translates the NISAR radar satellite's internal clock readings into standard world time (UTC).

How it's made. Generated for the NASA-ISRO Synthetic Aperture Radar (NISAR) mission's L-band radar.

How & where you'd use it. A purely technical housekeeping file used to time-stamp the satellite's data correctly; not a measurement and not used directly by general audiences.
